MOSES H. NABER, OF CHICAGO, ILLINOIS.

SHOCK-ABSORBER.

To all whom it may concern Be it known that I, Mosns H. NABER, a

citizen of the United States, residing ata new and useful spring device,which not only will cushion both the drop and rebound of the auto body,but will provide an increasing resistance to its rebound beyond thenormal position.

The invention consists in the matters hereinafter described and pointedout in the appended claims.

In the acompanying drawings Figure 1 is a view in elevation of a portionof an automobile equipped with my invention;

Fig. 2 is a perspective view of the absorber detached from theautomobile, and

Fig. 3 is a side view of the same.

In the drawings in which like letters of reference indicate the same orsimilar parts in the several views, the letter S designates the springportion of the device which is made of a single length of wire formedwith an upper and a lower wing by which it is respectively attached toopposing parts of the machine, the wings being formed by bending theends of the length of wire into loops each comprising a pair of parallelstrands w, 10. Each wing is thus adapted to receive a pair of clips 0,c, by which it is attached to its associated part of the ma chine; inthe application of the device illustrated in Fig. 1 the clips of thebottom wings are secured to the axle A and those of the top wings to thesprings B of an automobile. The clips are metallic plates each having aloop 0 at one end by which it is pivotally mounted on one of the strandsof a wing which are of suliicient length to afford a wide bearing forthe plates of the clips and to make it possible to use clips ofconsiderable width, and the clips are of suitable size or dimensions sothat each pair will en.- circle the associated part and have theiropposite or meeting ends secured together by suitable bolts and nuts asshown.

The wire of each absorber extends from its wings in a pair of arms 5, s,which pro- Specification of Letters Patent. Patented Jun 22 1920Application filed January 25, 1918, Serial No. 213,803.

ject from the outer ends of the wings in the same direction but -indifferent vertical planes and terminate in one or more vertical coils eand 6, respectively, the coils bemg disposed upon the inner sides of thearms so as to face each other and being arranged in horizontalalinement. The arms are angularly disposed to their wings and arediagonal or cross each other so that the arm of the upper wing mergeswith its coil at the lower portion thereof and the arm of the lower wingmerges with its coil at the upper portion thereof. The wire extendsreversely from the opposite portions of the coils toward or in thedirection of the wings in substantially horizontal legs 5 and I)", whichare in different vertical planes from each other and also from the arms8 and s, and which are united in any suitable manner as before by thehorizontally disposed coils b. The wings carrying the clips pro ject inopposite directions inwardly into the longitudinal vertical plane of thecoils 71 so that the clips of each absorber stand in vertical alinementat approximately the central line of the absorber.

Tn positioning the absorber it is placed between the axle and springwith the hori zontal coils 5 under the machine and in such position thatits clips will engage the axle and spring with the parts of the absorberin natural position so that it is neither compressed or extended to anyconsiderable extent. The bolts are then passed through the openings inthe meeting ends of the clips and fastened by suitable nuts. Theabsorbers are thus arranged according to the relation of the springs andaxles or other parts of the machine; in the arrangement shown in thedrawing as a typical example the axle and spring are parallel and so apair of the absorbers are connected to them as shown. The absorberscushion the drop downward of the body carried on the springs, and thediagonal disposition of each arm tends to put its vertical coils underan accumulating or increasing tension as its wing is moved away from itsneutral point or the normal separation of the wings is increased, so theabsorbers provide a gradually increasing resistance to the rebound ofthe body beyond its normal position and tend to stabilize the action ofthe springs 21115 to minimize shocks and vibrations resulting from theblows of high speeds or rough roads. The diagonal disposition of thearms ward thrusts of the axle, and as both these coils are placed underincreasing resistance or accumulate tension upon any abnormal separationof: their wings the rebound of the body is taken up and neutralized.

The absorber may be attached at any suitable point or location; I haveshown it attached between the auto spring and axle, but it may beotherwise located, as for example between the auto body and running gearor between the upper and lower portions of the auto spring.

I claim:

1. A shock-absorber for automobiles comprising a spring composed of alength of wire having an attaching wing at each end formed of parallelstrands, arms extending diagonally from the outer ends of the wings indifferent vertical planes, vertical coils at the ends of the arms in thesame horizontal plane and wound up when the wings are separated, and anintegral pair of-legs projecting reversely from the opposite portions ofthe coils and united in a suitably disposed bend, and clips mounted 011the strands of each wing. V

2. A shock-absorber for automobiles comprising a spring composed of alengh of wire having a wing at each endformed of parallel st ands, armsextending diagonally from the outer ends of the wings in differentvertical planes vertical coils at the ends of the arms in the samehorizontal plane, the arm of the upper wing merging with its coil at thelower portion thereof and tne arm of the lower wing merging with itscoil at the upper portion thereof, legs projecting from the oppositeportionsof the coils in opposite direction to the arms and terminatingin an intermediate set of horizontal coils, and clips on the strands ofeach wing.

In testimony whereof I affix my signature in presence of two witnesses.
